Please pray for that I now use a sharp things to cut into my skin in order that I can keep on praying

Please stop using sharp things to cut yourself. This does not help God to hear your prayers. God cares for you like a gentle and loving Father. He walks with us through pain and suffering. He doesn’t want us to cause pain and suffering to ourselves.

When Jesus was asked about prayer he said

We are told this story in Luke 11 (NIV): “1One day Jesus was praying in a certain place. When he finished, one of his disciples said to him, "Lord, teach us to pray, just as John taught his disciples.
2 “He said to them, ‘When you pray, say:
" 'Father,
hallowed be your name,
your kingdom come.
3Give us each day our daily bread.
4Forgive us our sins,
for we also forgive everyone who sins against us.
And lead us not into temptation.' "
5 “Then he said to them, ‘Suppose one of you has a friend, and he goes to him at midnight and says, “Friend, lend me three loaves of bread, 6because a friend of mine on a journey has come to me, and I have nothing to set before him.”
7"Then the one inside answers, 'Don't bother me. The door is already locked, and my children are with me in bed. I can't get up and give you anything.' 8I tell you, though he will not get up and give him the bread because he is his friend, yet because of the man's boldness he will get up and give him as much as he needs.
9"So I say to you: Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 10For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.
11"Which of you fathers, if your son asks for a fish, will give him a snake instead? 12Or if he asks for an egg, will give him a scorpion? 13If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!"

There is nothing in that story from Luke that Jesus teaches us that we should hurt ourselves in prayer. Jesus teaches that we should constantly ask for what is on our heart. We should not accompany that with our blood. Jesus’ blood is enough to cover any situation we have. He doesn’t need our blood too.
